Surface Patterning via Thiol‐Yne Click Chemistry: An Extremely Fast and Versatile Approach to Superhydrophilic‐Superhydrophobic Micropatterns

Abstract

An extremely fast and initiator-free approach to create superhydrophilic-superhydrophobic micropatterns via UV-induced sequential thiol-yne click chemistry is described. The photo­patterning can be performed at room temperature in a variety of solvents, including water, and can be also used for making high-density peptide or cell microarrays.
